[0037] See also Figure 1 and Figure 2 An electronic device (mobile phone) includes a waterproof member 1, a middle frame 2, a screen 3 and a battery cover 4. The waterproof member 1 is respectively arranged between the middle frame 2 and the screen 3 and between the middle frame 2 and the battery cover 4 to achieve sealing and waterproofing. Figure 2 The waterproof member 1 is manufactured as follows: the middle area 101 of the whole block of material is removed to form a closed ring-shaped waterproof member 1. The closed ring ensures airtightness and waterproof performance. In the manufacturing process of the waterproof member 1, the middle area 101 will be wasted, making the production cost of the waterproof member 1 high.

[0038] In order to solve the above problems, the present application discloses a waterproof member 1. The structure of the waterproof member 1 of the present application is described below in conjunction with the relevant drawings.

[0039] Figure 1 , Figure 3 , Figure 5 and Figure 7 A first waterproofing element 1 is shown schematically. Figure 8 A part of the third waterproof member 1 is shown schematically. Fig. 9 and Fig.11 The second type of waterproof component 1 is illustrated. These waterproof components 1 all include a plurality of waterproof portions 11. The material of the waterproof portion 11 is not limited, for example, foam glue. The industry also refers to the waterproof portion 11 as waterproof adhesive, or adhesive. The number of waterproof portions 11 is not limited to the four strips shown in the figure, and can be determined according to the structure of the waterproof object. When sold, a plurality of the waterproof portions 11 can be pre-spliced ​​onto the release film to form a disconnected sealing ring, or can be in an unspliced ​​state. In any case, as long as they can ultimately be spliced ​​into a ring shape according to the shape of the components that need to be waterproof (for example, the middle frame 2, screen 3 and battery cover 4 described later). Of course, based on the subsequent role of the waterproof portion 11, the structure of the waterproof portion 11 is not limited to the strip shape shown in the figure, and can ultimately be spliced ​​into a sealing ring. Because of the splicing, the disconnection forms a waterproof channel 12. Comparison Figure 6 and Figure 8 Although the waterproof channels 12 of the first waterproof component 1 and the second waterproof component 1 are both at the corners of the sealing ring, the difference is that the waterproof channel 12 of the first waterproof component 1 is perpendicular to the tangent of the arc corner, while the waterproof channel 12 of the second waterproof component 1 is not perpendicular to the tangent, but parallel to one side of the square ring. The difference between the third waterproof component 1 and the first waterproof component 1 is that the structure of the waterproof channel 12 is different, and the structure of the waterproof part 11 is different, as described later. In the embodiment of the present application, there are four waterproof parts 11, so there are also four waterproof channels 12. The waterproof channel 12 is used to accommodate a seal (the seal is not limited to the waterproof sealing glue 13 described later) so as to finally form a closed sealing ring.

[0040] As above, and Figure 3 and Figure 5 as well as Fig. 9 and Fig.11 and Figure 2 It can be seen from the comparison that when manufacturing the waterproof member 1, the whole block of material can be cut into a plurality of waterproof parts 11 (as shown in the figure, when the sealing ring is square, four sides are cut out first), and then the waterproof part 11 is spliced ​​to the release film to form the sealing ring (of course, as mentioned above, it can also be not spliced ​​to the release film). Based on this, for the whole block of material, if Figure 2 The middle area 101 shown will also be utilized and cut into the waterproof part 11 , thereby improving the utilization rate of the entire material and reducing the production cost of the waterproof part 1 .

[0041] Taking the waterproof part 11 spliced ​​onto the release film to form a sealing ring, the waterproof channel 12 containing the sealing glue 13 and the waterproofing of the relevant parts of the mobile phone as an example, the use of the waterproof part 1 is explained as follows:

[0042] See also Figure 8 Combined with Figure 6 , and see Fig.13 and Fig.12 Although the structures of the first waterproof member 1 and the second waterproof member 1 are different, the methods of use are the same. The methods of use are described as follows:

[0043] Tear off the release film, and stick the prepared waterproof part 1 on the middle frame 2 (if there is no release film, there is no need to tear off the release film, and the waterproof part 11 is directly stuck on the middle frame 2). Then, lay the middle frame 2 flat, and apply waterproof sealing glue 13 to the waterproof channel 12 (the state of the middle frame 2 after glue application can be seen with the help of Figure 8 To understand), the screen 3 is placed on the middle frame 2, and after being pressed with a jig, the screen 3 is bonded to the waterproof component 1. At the same time, the waterproof sealing glue 13 is pressed open, diffused along the waterproof channel 12, and fills the waterproof channel 12. After a period of time, the waterproof sealing glue 13 solidifies to form an effective seal.

[0044] Similarly, the same sealing method is used for the middle frame 2 and the battery cover 4. The prepared waterproof member 1 is attached to the battery cover 4. Then, the battery cover 4 is laid flat and waterproof sealing glue 13 is applied to the waterproof channel 12 (the state of the battery cover 4 after the waterproof sealing glue is applied can be seen with the help of Fig.13 To understand), the battery cover 4 is buckled onto the middle frame 2. After being pressed with a jig, the middle frame 2 is bonded to the waterproof component 1. At the same time, the waterproof sealing glue 13 is pressed open, diffused along the waterproof channel 12, and fills the waterproof channel 12. After a period of time, the waterproof sealant solidifies to form an effective seal.

[0045] Based on the enlightenment that the waterproof sealant 13 solidifies to form an effective seal, the waterproof channel 12 may not contain the waterproof sealant 13 but other seals as long as they can play the waterproof role.

[0046] The structure of the waterproof passage 12 in the embodiment of the present application is described below.

[0047] See also Figure 4 and Figure 6 Combined with Figure 3 and Figure 5 , see Figure 8 See also Fig. 9 , Fig.10 , Fig.12 and Fig.13 Combined with Fig.11 The waterproof channel 12 of the three waterproof parts 1 includes a receiving hole 121 and a first joint seam 122 and a second joint seam 123 connected to the receiving hole 121, so that the waterproof sealant 13 flows from the receiving hole 121 along the first joint seam 122 to the inner side of the sealing ring, and flows along the second joint seam 123 to the outer side of the sealing ring. The receiving hole 121 is at least used to hold the waterproof sealant for dispensing, so it is sufficient to play this role, and the structure is not limited to the structure shown in the figure. The position of the receiving hole 121 is not limited. Usually, the receiving hole 121 is centered in the width direction of the waterproof part 1, but it can also be offset from the center of the width direction (i.e., eccentric). For example, when the receiving hole 121 is eccentric, with the center of the receiving hole 121 as a reference, the distance that the waterproof sealant 13 flows from the center along the first joint seam 122 is L1, and the distance that the waterproof sealant 13 flows from the center along the second joint seam 123 is L2. Assume that L1<L2. The minimum effective waterproof width of the waterproof portion 11 is L3 (which can also be understood as the narrowest part of the waterproof portion 11). Figure 5 As shown, 2L1 = L3. In short, no matter which setting is used, effective waterproofing can be achieved.

[0048] As set up as above, on the one hand, only the gap and the edge need to be formed, the gap is spliced ​​into the accommodating hole 121, and the edge is spliced ​​to form the first splicing seam 122 and the second splicing seam 123 accordingly, which will not increase the manufacturing difficulty of the waterproof component 1, and will not cause material waste, etc., thereby improving the utilization rate of the entire material and reducing the production cost of the waterproof component 1; on the other hand, the accommodating hole 121 is used to hold the waterproof sealing glue 13, and the fluidity and viscosity of the waterproof sealing glue 13 are used to achieve sealing and waterproofing, the sealing is simple, and the waterproof effect is good, for example, it can achieve IP68 waterproofing.

[0049] For the first waterproof member 1 and the second waterproof member 1, the waterproof channel 12 has at least one of the following characteristics:

[0050] a) See Figure 4 , Figure 6 and Figure 8 Combined with Figure 3 and Figure 5 The shape of the receiving hole 121 is circular, or it can be elliptical, square or regular polygonal.

[0051] As set above, since the shape of the glue discharged from the glue dispensing machine is finally circular, the shape of the accommodating hole 121 is circular, elliptical, square or regular polygonal, which is the same as or closer to the final shape of the waterproof sealing glue 13. Therefore, it is convenient for glue dispensing and prevents the waterproof sealing glue 13 from contaminating other components.

[0052] b) See Figure 4, Figure 6 and Figure 8 Combined with Figure 3 and Figure 5 , the first joint seam 122 and the second joint seam 123 are located on the same straight line.

[0053] As set up above, the first splicing seam 122 and the second splicing seam 123 are located on the same straight line. On the one hand, the structural requirements for the tool for cutting materials are low. For example, the shape of the tool only needs to be a straight line. On the other hand, the waterproof part 11 can be cut out by a straight line tool, and the waterproof part 11 is easy to manufacture.

[0054] c) See Figure 4 , Figure 6 and Figure 8 Combined with Figure 3 and Figure 5 , the width of the first joint seam 122 is equal everywhere along the length direction of the first joint seam 122. The width of the second joint seam 123 is equal everywhere along the length direction of the second joint seam 123. The length direction of the first joint seam 122 and the length direction of the second joint seam 123 can both be considered as the direction away from the receiving hole 121. Figure 4 and Figure 6 As shown by the arrows A1 and A2, as described above, no matter the width of the first joint seam is equal everywhere or the width of the second joint seam is equal everywhere, the waterproof sealant can be distributed more evenly and the waterproof effect is better.

[0055] See also Fig.10 , Fig.12 and Fig.13 Combined with Fig. 9 and Fig.11 For the third waterproof member 1 , the receiving hole 121 includes a drainage portion 1211 . The width of the drainage portion 1211 gradually decreases toward the outside of the sealing ring and is communicated with the second joint seam 123 .

[0056] As described above, since the width of the drainage portion 1211 gradually decreases toward the outside of the sealing ring and is connected to the second joint seam 123, the guiding effect of the drainage portion 1211 allows the waterproof sealant 13 in the receiving hole 121 to flow outwards better along the second joint seam 123. After the waterproof sealant 13 is cured in the waterproof channel 12, during the waterproof test, the waterproof sealant 13 can prevent water from flowing to the inside of the sealing ring (that is, flowing to the inside of the whole machine), so that the waterproof channel 12 and the waterproof sealant 13 of the above structure are combined with the waterproof portion 11 to achieve good waterproof performance at a low cost, for example, IP68 waterproof can be achieved.

[0057] For the third waterproof member 1, the waterproof channel 12 includes at least one of the following features:

[0058] a) See Fig.10 , Fig.12 and Fig.13 Combined with Fig. 9 and Fig.11 The drainage portion 1211 includes symmetrical arcuate walls 1212, each of which is smoothly connected to the side wall corresponding to the second joint, and the smooth connection is, for example, tangent, so that the arrangement of the arcuate walls 1212 makes the drainage portion 1211 drop-shaped. Based on the idea that the drainage portion 1211 gradually decreases toward the outside of the sealing ring, the drainage portion 1211 may also include symmetrical planes, each of which is smoothly connected to the side wall corresponding to the second joint. Because the width of the drainage portion gradually decreases, each plane is inclined toward the outside of the side wall corresponding to the second joint.

[0059] As configured above, when the drainage portion 1211 includes an arcuate wall 1212 or a plane, combined with the gradual reduction of the drainage portion 1211 toward the outside of the sealing ring, it is easier for the waterproof sealing glue 13 to flow toward the outside of the waterproof component 1.

[0060] b) See Fig.12 and Fig.13 In the third waterproof component 1, the first splicing seam 122 includes a square portion 1221 directly connected to the receiving hole, and the first splicing seam 122 is square as a whole. Of course, in the first splicing seam 122, only the square portion 1221 may be square. Regardless of whether the first splicing seam 122 is square as a whole or only the square portion 1221 is square, the width of the square portion 1221 is not greater than the minimum width of the drainage portion 1211. In an embodiment of the present application, the minimum width of the drainage portion 1211 is equal to the width of the second splicing seam 123, and the width of the square portion 1221 is equal to the width of the second splicing seam 123. Based on the role of the subsequent square portion 1221, as an alternative embodiment, the first splicing seam includes a flared portion directly connected to the receiving hole, the width of the flared portion increases toward the inner side of the sealing ring, and the minimum width of the flared portion is not greater than the minimum width of the drainage portion.

[0061] As set up above, since the width of the square portion is not greater than the minimum width of the drainage portion 1211, or the minimum width of the flared portion is not greater than the minimum width of the drainage portion, the square portion 1221 or the flared portion of this structure is directly connected to the accommodating hole 121, which increases the resistance of the waterproof sealing glue 13 when it flows, so that when the waterproof sealing glue 13 flows to the inner side of the sealing ring, it is not easy to flow in too much, which can prevent the waterproof sealing glue 13 from flowing into the interior of the whole machine and causing pollution to the interior of the whole machine.

[0062] See also Fig.12 Combined with Fig.13 and Fig.10 For the third waterproof member 1, when the drainage portion includes an arc-shaped wall, the first joint seam 122 and the second joint seam 123 are distributed at an obtuse angle. Fig.12 The obtuse angle is indicated as a.

[0063] As set up as above, since the first splicing seam 122 and the second splicing seam 123 are distributed at an obtuse angle, the portion between the first splicing seam 122 and the second splicing seam 123 can be made larger, so that the curvature of the arc-shaped wall 1212 is larger and is more smoothly connected to the side wall of the second splicing seam 123, and further, the guiding effect of the drainage portion 1211 is better, so that the waterproof sealing glue 13 can flow outward better.

[0064] Combination Fig. 9 and Fig.10 Based on the function of the drainage portion 1211 of the third waterproof member 1, the third waterproof member 1 is more suitable for the case where the sealing object is a 3D curved surface, for example, the battery cover is a 3D curved surface. Fig.10 and Fig. 9 As shown, the waterproof channel 12 (accommodating hole 121, first joint seam 122 and second joint seam 123) is bent from the inside to the outside of the sealing ring, as shown in FIG. Fig.10 The bending direction F is indicated. Fig. 9 and Fig.10 In the embodiment, the waterproof portion 11 also extends in the bending direction. Of course, the skilled person can understand that as long as at least the portion corresponding to the waterproof channel 12 is a curved surface, that is, the waterproof portion 11 includes an end portion 111 constituting the waterproof channel 12. In the waterproof portion 11, at least the end portion 111 is a curved surface, and the curved surface is curved in the direction from the inside to the outside of the sealing ring.

[0065] Of course, the waterproof channel 12 with the aforementioned receiving hole 121 including the drainage portion 1211 can also be applied to the case where the sealed object is a plane, but in this case, the waterproof channel 12 extends on the plane. The plane can refer to the description of the first waterproof member 1 and the second waterproof member 1 below.

[0066] For the first waterproof member 1 and the second waterproof member 1, because they are planar structures, that is, see Figure 7 Combined with Figure 4 and Figure 6Each of the waterproof parts 11 includes a top surface 112 and a bottom surface 113 opposite to each other in the thickness direction, and the top surface 112 and the bottom surface 113 are planes. In this way, the first waterproof member 1 and the second waterproof member 1 can be applied to the case where the sealed object is a plane. Of course, the sealed object is a plane including the following cases: 1) the planes are the same plane; 2) multiple planes are of different heights and connected in a stepped shape.

[0067] See also Figure 3 , Figure 5 , Fig. 9 and Fig.11 In some embodiments, the three sealing rings are square rings, and the corners of the square rings are rounded. Of course, in other embodiments, the corners are right angles.

[0068] As described above, the sealing ring is a square ring, corresponding to the waterproof part 11 being in a straight strip shape, so that the same material can be cut into more waterproof parts 11, further improving the utilization rate of the material and reducing the production cost of the waterproof part 1. It should be pointed out that the aforementioned straight strip shape refers to the overall appearance of being straight, and can be of different widths as shown in the figure, or can have a part with rounded corners as shown in the figure, as long as the aforementioned improvement in material utilization is achieved.

[0069] In the second aspect, the present application discloses an electronic device, such as a mobile phone or other electronic device with waterproof requirements. The electronic device includes a waterproof portion of any of the aforementioned waterproof components 1 (that is, the electronic device does not include the release film, and reference can be made to the aforementioned description of the method of use of the waterproof component 1), a first component (such as the aforementioned middle frame 2), a second component (such as the screen 3 or the battery cover 4) and a filler. The plurality of waterproof portions 11 are in sealed contact with the first component and the second component, and the filler seals the waterproof channel 12 and is in sealed contact with the first component and the second component to isolate the inside and outside of the electronic device. The relationship between the filler, the first component, the second component and the waterproof portion 11 can be found in the aforementioned description of the method of use of the waterproof component 1.

[0070] In some embodiments, the filling piece is formed by curing the waterproof sealing glue 13 .

[0071] As described above, since the filling piece is formed by curing the waterproof sealant 13, the waterproof effect is good and can reach IP68 waterproof.

[0072] The above description is only a preferred implementation mode of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
